PMR spectra have been used in establishing the structure of ten bromo-, nitro-, and amino-substituted 10,10-dimethyl-10-sila-2-azaanthrones. Anomalous effects of NO/sub 2/ and NH/sub 2/ groups adjacent to the carbonyl carbon have been observed and explained; these effects are related to the specific geometry of these molecules.
